How do I tell a real from fake Gucci Fedora hat?

I am selling a Gucci hat I just recieved and I am not crazy about it. I just need to know if it is real or not. The tag on the inside says "Made in Italy" and I am preety sure that if it was fake it would say "Made in China". Also, how much should I sell it for. It is a brand new hat. Thanks!
